The European Union and the National Science Foundation have been collaborating on a joint international project to identify future research directions and funding priorities for digital libraries. Five working groups were established to explore specific research areas: Intellectual Property and Economics, Global Resource Discovery, Interoperability, Metadata, and Multilingual Information Access. At their most recent workshop in October 1998, the five working groups presented recommendations based on their studies, the results of which are outlined in this Summary Report (available in HTML, Word, and .pdf). The final reports from each of the five working groups are expected to be published in early 1999. The collaborative work on digital libraries by the National Science Foundation and the European Union is described briefly in the Summary of Research Agenda. Also included here are links to European digital library research and initiatives.
